MECHANICAL MOVEMENT.

Specification of Letters Patent.

Patented Nov. a, rare.

Application filed May 4, 1914. Serial No. 836,110.

To all whom it may concern:

Be it known that I, FRANK Sonnrnn, a citizen of the United States, and resident of Barberton, in the county of Summit and State of Ohio,have invented certain new and useful Improvements in Mechanical Movements, of which the following is a specification.

This invention relates to an improvement in mechanical movements, having reference especially to means for converting continuous rotary motion into reciprocating motion having different paths of travel.

The invention is more particularly designed for actuating a feeder by means of which successive-blanks or sections, as rapidly as they are severed from a strip of material, are advanced to boXforming or other mechanism.

The object of the invention is to provide a mechanical movement of the character mentioned, which shall be simple and durable in construction and uniform and positive in operation.

To this end the invention consists, primarily, in a rotatable crank element, a rockelement and a feed-element having spaced pivotal connections with said crank and rock .elements respectively.

The invention also comprises features of construction which will be hereinafter described and claimed.

In the drawings Figure 1 is an end elevation of amechanical movement embodying my invention, the same being represented as applied to a blank pusher or feeding head for boX-shuck making machines, or the like. Fig. 2 is a side elevation, the parts being illustrated in the relative positions which they occupy preparatory to the horizontal feeding action of said head on the opposing blank. In this view the paths of movement of the head are indicated in dotted outline. Fig. 3 is a similar view showing the parts in relative positions which they occupy during a part of the return movement.

10 designates a continuously driven shaft having fast thereon a crank disk 11.

12 designates an angular feed-frame, one member 13 of which is provided with two oppositely extending arms 14, 15. One of these arms has a wrist-pin connection, as at 16, with the crank-disk, and the other arm is pivotally connected to a rocker-arm 17 which is pivoted to a stationary support, such as the brackets 18. The free end of the upper arm of the frame 12 bears a pusher-head 19 which overhangs a horizontal guide-structure 20 to which blanks (as 21) may be successively fed from a suitable source of supply.

By the construction just described the continuously rotating crank disk rotates about its axis 10 the pivotal or wrist connection. 16 of the arm 1A of the angular feed-frame, and the other arm 15 of said frame is pivotally supported and caused to travel by the rocker arm 17 in a horizontal arc described from the axis of oscillation of the latter, the resultant of these motions as translated to the free end of the feedframe and its pusher head being the move ment defined by the dotted lines in Fig. 2, that is to say, the head is moved forward in a. horizontal plane, so as to impinge against and advance the opposing blank, and is then returned in an arched or curved path over the horizontal, plane of the blank and brought into active position relative to the outer edge of the next succeeding blank. and so on.

Ihe mechanical movement above-described is simple and durable in construction and smooth and positive in its operation. Thereby is avoided the use of a multiplicity of cam and gear connections to accomplish the described compound feeding and return motion.

I claim- Mechanism of the character described comprising a rotatable crank element, an angular feed-frame provided with two oppositely-extending arms, one of which has a pivotal connection with the crank element. and a rocker pivoted to the other arm of said frame, whereby the forward end of said frame is moved forward in a horizontal path and is then returned in a curved path to position for a succeeding forward movement.

Signed at Barberton in the county of Summit and State of Ohio this 29th day of April A. D. 1914.
